A large proportion of healthy African Americans have been observed to have a white blood cell count (WBC) that is persistently lower than the normal range defined for individuals of European ancestry [1]â[5].
Energy is only released when chemical bonds are formed. In general, a chemical reaction involves two steps: 1) the original chemical bonds between the atoms are broken, and 2) new bonds are formed. These two steps are sometimes lumped into one event for simplicity, but they are really two separate events.
When chemical bonds are formed, heat is released in an exothermic reaction. There is a loss of kinetic energy in the reacting electrons, and this causes energy to be released in the form of light. This light is equal in energy to the stabilization energy required for the chemical reaction (the bond energy).
